Cisco BTS 10200 Softswitch

Cabling, VLAN, and IRDP Procedures

The purpose of this procedure is to explain how to:

•Cable a new Cisco BTS 10200 Softswitch system

•Provision the virtual local area network (VLAN) on the Cisco 2924M Ethernet Switches (hubs)

•Enable Internet Control Protocol (ICMP) Router Discovery Protocol (IRDP) functionality on the

Cisco BTS 10200 Softswitch and on the Cisco routers adjacent to the Cisco BTS 10200 Softswitch

This procedure is applicable to a Cisco BTS 10200 Softswitch with active and standby components

colocated in the same office.

Note This procedure is applicable only to systems with Continuous Computing hardware. If you are using

other hardware, contact your Cisco account team for procedures.

This procedure is not applicable to Cisco BTS 10200 Softswitch systems that are already in service.

Caution Do not use this procedure to change the cabling of an in-service Cisco BTS 10200 Softswitch, because

that will cause interruption of service. It is not necessary to change the cabling of in-service systems to

match this document.

Labeling the Cables

4. To support full system redundancy, it is necessary to connect each of the three

Cisco BTS 10200 Softswitch external uplinks to a different network with diverse routing paths to

the related external network elements (NEs) and services (such as OSS, DNS, media gateways, and

announcement servers).

Caution If each of the three external uplinks is not connected as described in Note #4, a single point of failure

could cause a traffic interruption.

5. To ensure redundancy of the DNS lookup function in the event of a network outage, it is strongly

recommended to have two DNS units reachable via separate networks with diverse routing paths.

Caution If both DNS servers become unreachable, a traffic interruption will occur.

Note Ethernet ports on the rear panels of some EMS and CA units are labeled ETH0, ZNB0, ZNB1, and so

forth. On some units these ports are labeled hme0, qfe0, qfe1, and so forth. Regardless of the labeling

style, the Cisco BTS 10200 Softswitch functionality is the same.

Labeling the Cables

Make sure that you have all the cables labeled before you begin. Label the cables according to the

procedure in Appendix A: Cable Labeling, page 22.

Connect Ethernet Cables To EMS and CA Units

Follow these steps to connect the Ethernet cables. Refer to Figure 1 on page 2 to identify the specific

units in the rack.

Step 1 Obtain the 10 Ethernet cables needed for connections between the rear panel of the Element

Management Systems (EMS A and EMS B) and the two Cisco 2924M Ethernet Switches (Hub A and

Hub B). These cables are listed in Table 1 in Appendix B: Cable List, page 23.

Step 2 Connect the 10 Ethernet cables to the ports on the rear panel of the EMS units as listed in Table 1 in

Appendix B: Cable List, page 23.

Figure 3 shows the rear view of the EMS. On the EMS, use ports ETH0 and ZNB0 through ZNB3.

Note Figure 3 and Figure 4 are not to scale.

Step 3 Obtain the 18 Ethernet cables needed for connections between the rear panel of the Call Agents (CA A

and CA B) and the two Cisco 2924M Ethernet Switches (Hub A and Hub B). These cables are listed in

Table 1 in Appendix B: Cable List, page 23.

Step 4 Connect the 18 Ethernet cables to the ports on the rear panel of the CA units as listed in Table 1 in

Appendix B: Cable List, page 23.

Figure 4 shows the rear view of the CA. On the CA, use ports ETH0 and ZNB0 through ZNB7.

Connect CCPUnet Cables and Terminating Resistors

Note These two CONSOLE cables are specially designed for the CONSOLE connections. Make sure

that you are using the correct cables.

Note One end of the CONSOLE cable is labeled “switch” and the other is labeled “net CCN”. The

“switch” end must connect to the Hub and the “net CCN” end must connect to the Alarm Panel.

Step 1 Refer to Figure 1 on page 2 to identify which Cisco 2924M Ethernet Switch (Hub) is designated

Ethernet Switch A and which is Ethernet Switch B.

Step 2 Connect the “net CCN” end of a CONSOLE cable to port SER 1 on the Alarm Panel, and the “switch”

end to the CONSOLE port on the rear panel of Ethernet switch (Hub) A.

Step 3 Connect the “net CCN” end of a CONSOLE cable to port SER 2 on the Alarm Panel, and the “switch”

end to the CONSOLE port on the rear panel of Ethernet switch (Hub) B.

The rear view of the alarm panel is shown in Figure 5. (The drawing is not to scale.)

Figure 5 Rear View of Alarm Panel

Connect CCPUnet Cables and Terminating Resistors

Follow these steps to connect the intershelf signaling (CCPUnet) cables and terminating resistors:

Step 1 Obtain the eight CCPUnet cables (four for CCPU A and four for CCPU B).

Step 2 Connect the CCPUnet cables between the machines as listed in Table 1 on page 23. Make sure that you

connect cables labeled CCPU A to the CCPU A ports, and cables labeled CCPU B to the CCPU B

ports.

Note Refer to Figure 3 through Figure 5 to locate the CCPU ports on the rear panels.

Step 3 Connect the two terminating resistors (part # CCPU 012 02150-02602 REV 00) to the Alarm Panel

(Figure 5) as follows: Connect one resistor to CCPUNet HUB A port 5, and the other resistor to

CCPUNet HUB B port 5.

Connect External Network Uplink Cables to Ethernet Switches

Follow these steps to connect the external network uplink cables to the Ethernet switches:

Step 1 Refer to Figure 1 on page 2 to identify which Cisco 2924M Ethernet Switch is designated Ethernet

Switch A and which is Ethernet Switch B.

Step 2 If your local network documentation calls for gigabit Ethernet, contact Cisco TAC for assistance.

Step 3 If your local network documentation calls for 100 Mb Ethernet, connect the applicable network uplink

cables as listed in Table 1. Ports #21 through 24 are available for this use.

Step 4 After installing the uplink cables, record the necessary information on a copy of Table 1 or similar

document according to local procedures.

Connect SS7 Signaling Cables To CA

Follow these steps to connect the SS7 signaling cables to the CA units of the

Cisco BTS 10200 Softswitch:

Step 1 Refer to Figure 1 on page 2 to identify which unit is CA A and which is CA B.

Step 2 Connect T1 cables for SS7 signaling to the SPE0 and SPE1 connectors on CA A (see Figure 6).

Note SPE2 and SPE3 are not used.

Step 3 Connect T1 cables for SS7 signaling to the SPE0 and SPE1 connectors on CA B.

Step 4 Route the other ends of these T1 cables as specified in local network documentation, and add (write in)

this information on a copy of Table 1 or similar document.

Connect Site Power and Grounding Cables To PDU

Step 2 Following local electrical codes, connect the ground cables from each of the devices in the rack to the

PDU grounding point (either of the two grounding screws on the PDU rear panel). See Table 1 for the

complete cabling list.

Connect Site Power and Grounding Cables To PDU

After obtaining approval from a supervisor, an authorized power installer should follow these steps to

connect the DC power from the office batteries to the PDU.

Note For DC systems the nominal current rating for a complete Cisco BTS 10200 Softswitch system

is 26A at -48 VDC, and the maximum current rating is 40A at -48 VDC.

Note If you need to connect an AC system, contact your Cisco account team for assistance.

Step 1 Following local electrical codes, connect power cables from the power distribution unit (PDU) to dual

feeds (“A” and “B”) on the office batteries. Use Listed two-hole crimped lugs on the PDU side of the

cable.

Step 2 Following local electrical codes, connect the PDU grounding point (both of the two grounding screws

on the PDU rear panel) to CO earth ground using 6 AWG wire or heavier and a Listed two-hole crimped

lug.

Warning

This equipment must be grounded. Never defeat the ground conductor or operate the equipment in
